Mobile phones features have become more diverse, with digital camera, movie and video, GPS navigation, and TV functionality.
As a result, there is an increasing need to downsize devices, lighten structure, reduce components, and achieve traditional hardware operations with software solutions.
An embedded software solution that operates lightly and decreases the CPU load on mobile devices is in strong demand from developers.
The H.264/MPEG-4 AVC codec (for encoding/decoding) has been widely discussed as a next generation video compression/decompression standard.
The codec opens up many new possibilities in various applications, including satellite digital TV broadcasting, video distribution over Internet, and high definition compliant next generation DVD, among others.
Conventional H.264 video compression requires a large number of arithmetic operations, and additional components such as a dedicated H.264 LSI, or high-speed DSP application processors.
However, the new Techno Mathematical H.264/MPEG-4 AVC codec can produce QCIF (176 x 144 pixel) video content of 15-40frame/s processing using only a 32bit/150MHz CPU and 16bit/8MHz external memory.
As mobile CPU clock speeds and memory capacities further increase, larger videos - QVGA (320 x 240 pixel) or VGA (640 x 480 pixel) - can be supported by the decoder with increases in frame speed up to 30frame/s.
Techno Mathematical is currently developing more complex software for encoding H.264/MPEG-4 AVC standard video involving further arithmetical operations.
This software is due for completion in April.
